Protecting your data from prying eyes is more important than ever before. Still, we often forget to lock our computers when we walk away or purposely don’t bother because it’s too much of a pain to retype in a password every time you move to and fro. For this, Untethered Labs created Gatekeeper, a key fob sized wireless “lock and key” for your computer that automatically locks your computer when you walk away from it and unlocks it when you return.

It’s a pocket Bluetooth 4.0 enabled system that consists of a small rectangular coin-cell battery-operated key fob, a USB dongle and a companion app. The company’s latest model, Gatekeeper 2.0, which we’re reviewing here today, is updated and redesigned; At 45 mm x 25 mm x 6 mm and weighing 10 grams, it’s lighter and 20% thinner and with better range detection. The new sleeker fob has a rubberized matte finish, so it won’t slip from your hands with a built-in loop to secure it on a safety keychain attachment or lanyard – both included. The USB lock or dongle is half the size and now has a metal shield. The Android and iOS apps have been updated as well as the software for Windows and Mac although the Mac version is still in beta.
